VAULT-I|IGHT, FLOOR-LIGHT, PAVEMENT-LIGHT, OR SKYLIGHT CONSTRUCTION.

Specification of Letters Patent.

Patented Oct. 2,191.7.

Application filed May 15, 1912. Serial No. 697,381.

To all whom it may concern Be it known that I, ANTHONY ELTON DAVIS, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Vault-Light, Floor-Light, Pavement-Light, or Skylight Construction, of which the following is a specification.

My present invention relates to a vault light, floor light, pavement light or skylight construction in which a plurality of reinforced concretebeams or lintels are employed which form the support for the lenses or tiles and which are preferably provided with bonding elements in order to interlock with. a second layer of binding materialsuch as concrete for example, which surroundsthe lenses and is anchored to the beams 0r lintels in such a manner that the expansion and contraction of the concrete construction will be substantially uniform throughout its mass,

With the above and other objects in view which will hereinafter more clearly appear in. the detailed description, my invention consists of a novel vault light, floor light, pavement light or sky light construction which maybe very economicallymanufac- .tured and assembled. and which may be completed at the place of installation by unskilled labor with consequent decrease in thecost of production.

It further consists of a novel construction ofa vault light, floor light, pavement light orsky light construction comprising a plurality of reinforced concrete beams or lin tels which are spaced apart in order to form openings adapted to be covered by the lenses or tiles and such beams on lintels may be spaced apart in a variety of ways, and if desired, they may be provided with arms integral therewith or secured thereto, and

sueharms may interlock with the beams or lintels or be secured thereto in any desired manner. I

Myinvention further consists ofa novel vault light, floor light, pavement light or sky light construction in which reinforced beams on lintels are provided on their up per .faces with anchoring or bonding ele' ments, and with laterally extending spacing members which form openings adapted to be covered by the lenses or tiles, and after the lenses or tiles are placed in position, a

layer of concrete is. formed which surrounds the lenses and interlocks with the bonding* or anchoring elements, whereby the layer of concrete formed in site, is bonded with the preformed beams or lintels.

It further consists of. other novel fcatures of OOllSl'lllOlZlOIlyitll as will be hereinafter fully set forth. 1

For the purpose of illustrating my invention, I have shown in the accompanying drawings, preferred embodiments thereof it whichare at present preferred by me, since thesame have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of whichmy invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and orgaiiization of these instrumentaliticsas herein shown and described.

Figure 1 represents a perspective views of a vault light-,floor light, pavementlight one type of beam or lintel which maybe advantageously employed.

Figs. 5, 6, 7, S and 9 represent, rcspectively, perspective views of otherembodiments of my invention.

Similar numerals of reference corresponding parts in the figures.

Referring to the drawings:

The reinforced concrete beams or lintels 1 are preferably preformed and consist of reinforcements 2 of any desired nature, embedded in concrete and it is to be under stood that the contour of the beams may vary widely in practice.

The upper face of the beams or lintels may have any desired conformation but are preferably flat and are provided with bonding or anchoring elements 3 of any desired nature and in the different embodiments of indicate my invention I have shown different types 1 pavement light or sky i in Fig. 6.

ance with the conditions met with in practice and with the shape of the opening 5.)

After the lenses 6 are placed in position a layer of concrete or other binding material 7 is placed onthe beams 1 and the spacing arms a .to interlock with the bonding or anchoring elements 3 and surround the lenses 6 preferably flush with the upper face thereof. In the present instance,.the lenses 6 employed are provided with ribs or beads 8 in order that a better interlocking of the lenses with the layer 7 of concrete formed in situ will be produced. The layer of concrete 7 is bonded to the preformed beams or lintels by means of the anchoring elements 3 so that a relnforced concrete constructlon is attained.

In the embodiment seen in Fig. 3 instead of having the spacing bars integral with the beams or lintels Iemploy a, reinforced concrete. lintel 9 having recesses 10 inv its upper faces with which the reduced neck '11 of spacing bars 12 interlock, said spacing bars and lintels forming openings. 13 to be covered by lenses in the same manner .as the embodiment seen in F is. 1, it being noted that bonding elements 1% of any. desired type are carried by the lintels 9.

In the embodiment seen in Fig. 5, the construction is similar to Fig. 1 except that strips 15 are employed secured to the lintels by pins 16. which, if desirechproject upwardly to form bonding elements.

In the embodiment seen in Fig. .6, a different manner of securing together the lintels is shown, a reinforced concrete lintel 17 having a spacing arm integral therewith, theendof which forms a dovetail joint as at 18, with the adjacent lintel. A different construction of bonding element is shown In thev embodiment seen in Fig. 7, the

spacing arms 19 have a lip 20 interlocking with a recess 21 in the adjacent lintel, a different type of bonding element being shown.

In the embodiment seen in Fig. 8 a reinforced concrete lintel 22 has rectangular shaped recesses 23 on opposite sides thereof adapted to receive short spacmg bars 2 1,

and a different type of bonding element is shown.

In theembodiment seen in Fig. 9,26 designates a reinforced concrete lintel having straight spacing arms 27, the ends of which seat in correspondingly shaped recesses 28 in an adjacentlintel and are secured thereto by fastening devices 29. The bonding elements 30 are shown as consisting of concrete projections of greater dimensions at theirouter end than they are at their inner ends.

It will now be clearly apparent that in all the embodiments of'my invention herein illustrated a reinforced concrete lintel having any desired contour is formed which when. installed is spaced from an adjacent lintel in such a manner as to form openings adapted to be covered with lenses or tiles, and after such lensesor tiles are placed in position, they are surrounded with concrete or other binding. material which also embeds the bonding elements in case they are employed. 4

my inventionwhether or not the lintels are spaced from each other by spacing members integral therewith or separate therefrom. It is also immaterial whether or not the spacing arms are in contact with interlock with or are'secured to an adjacent lintel.

Any desired type of bonding or anchoring elements may be. employed. In my novel construction the expansion and contraction of the concrete does not place undue strain on the. glass and thereby eliminates in a large measure the breaking-of the lenses or tiles. 1

I prefer in practice to preform the lintels, but if desired they may be made at the place of installation. I

It will now be apparent that I have devised ainoveland useful construction of a vault light, floor light, pavement light or sky light construction which embodies the features of. advantage enumerated as desirable in the statement of the invention and theabove description, and while I have, in the present instance. shown anddescribed preferred embodiments thereof which have ters Patent, is
